There’s a refreshing sense of nostalgia in “Teenage Mutant Ninja Turtles: Mutant Mayhem” — and it doesn’t just have to do with the fact that the eternally youthful ninja turtles have been around since the 1980s, in the form of the original comic book series, as well as TV adaptations, films, toys and video games. After all, what’s more adolescent than that? Now, as teenagers, the turtles — pugnacious Raphael (Brady Noon), doofy Michelangelo (Shamon Brown Jr.), nerdy Donatello (Micah Abbey) and their ever-earnest leader, Leonardo (Nicolas Cantu) — dream of having a normal life with humans. But the aboveground masses face their own threat: Another mutated creature, Superfly (Ice Cube), aims to overtake the human world, Magneto-style. The turtles team up with a student journalist named April (Ayo Edebiri) to try to save the day and hopefully be accepted into human society.
